Summary

Hirai and Eyring’s notion of holes in a liquid lattice has been employed to demonstrate the effect of pressure on the various contributions to the total ultrasonic absorption in toluene and hexane in the pressure range (1⧀v10000) kg/cm2. Under some specific assumpons, the pressure dependence of the thermal relaxation time for these Kneser-type liquids has also been exploited.

Riassunto

Si è usato il concetto di buche in un reticolo liquido dovuto a Hirai ed Eyring per dimostraıe l’effetto della pressione sui vari contributi all’assorbimento ultrasonico totale nel toluene e nell’esano nel campo di pressioni (1⧀v10000) kg/cm2. Facendo alcune ipotesi specifiche, si è anche sfruttata la dipendenza del tempo di rilassamento termico della pressione per questi liquidi del tipo di Kneser.

Резюме

Было использовано описание Хирея и Иринга дырок в жидкой решетке для исследования влияния давления на различные вклады в полное ультразвуковое поглощение в толуоле и гексане в области давлений от 1 до 10000 кг/см2. С помощью некоторых специальных предположений была также изучена зависимость от давления времени тепловой релаксации t для этих жидкостей, кнесеровского типа.
